6. 6 System Concepts A system is an integrated set of components, or entities, that interact to achieve a particular function or goal. A component of a system can be a physical component an abstract concept A component of a system may be another system. A system may be a component of another (bigger) system. Every system has a boundary, inputs, outputs and method for converting inputs to outputs and system interface. A system are composed of interrelated and interdependent subsystems.

7. 7 System Boundary and Interface A system boundary depicts the scope of activities. For instance, the activities in a class include lectures, discussion, testing, grading and preparation of lectures, assignment, etc. These activities may represent the boundary of the system for which the teacher is responsible. Thus, the boundary delineate an area of responsibility. Systems usually consists of numerous sub-systems which has elements, interactions and objectives. Sub-systems perform specialized tasks related to the overall objectives of the total system. Sub-systems must work harmoniously to achieve the primary objective of the system. An interface is a connection at systems or subsystem boundaries. An interface serves as a medium to enter inputs or to show outputs.

8. 8 Systems & Their Environments System’s environment is any system (other systems, in general) outside the system. System’s environment may or may not interact with the system. Open system is a system that interact with its environment. An open system needs to receive feedback to change and to continue to exist in its environment. Feedback is needed to measure the performance of the system and then to improve the system. Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal. Closed system is a relatively self-contained system (does not interact with its environment).

11. 11 What is an Information System? An IS can be defined as an organized combination of people, hardware, software, communication networks, and data resources that collects, transforms, and disseminates information in an organization. IS Resources People Software Hardware Data Networks

12. 12 Components of an Information System

13. 13 IS Recources People resources Specialists (system analysts, software developers, system operators) End users Hardware resources Machine (computers, printers, scanners, etc.) Media (magnetic disks, optical disks, tapes, etc.) Software resources System software + utilities Application software Data resources (product descriptions, HR, etc.) Network resources (Communication media, communication processors, networks access, etc.)

14. 14 Data and Information Data: raw facts, such as an employee’s name and number of hours worked in a week, inventory part numbers, or sales orders. Information: a collection of facts organized in such a way that they have additional value beyond the value of the facts themselves.

18. 18 Attributes of Information Quality
